SN1 SN2 E1 E2 Kinetics First order Second order First order Second order Leaving Group (LG) LG determines reaction rate Better LG increases reaction rate LG determines reaction rate, same as SN1. Better LG increases reaction rate Nucleophile (Nu) Better Nu competes for end product, but does not affect kinetics. Better Nu increases reaction rate. Sterically hindered nucleophiles favor elimination. Strong Bases that are sterically hindered.
